We have multiple users editing the same large API. Is there any way to (a) notify others when a specific user's changes are saved and/or (b) distinguish those changes from others (similar to "git blame")?
I have opened two enhancement requests, one for point a and one for point b. Currently you can not do this in Swaggerhub, the enhancement requests should add this functionality when they are implemented.
By the way, Swaggerhub integrates with Github and Bitbucket. When you sync your spec with Github or Bitbucket from Swaggerhub you can possibly achieve this with the integration with those products until this is implemented in Swaggerhub.
